1 VG7000 Series Bronze Control Valves Installation Instructions VG , Re v. K Part No , Rev. K Issued March 2016 Applications VG7000 Series Bronze Control Valves are primarily designed to regulate the flow of water and steam in response to the demand of a controller in Heating, Ventilating, and Air Conditioning (HVAC) systems. Contact the local Johnson Controls representative for compatibility concerns before using the VG7000 Series Bronze Control Valves Technical Specifications table at the end of this document. These installation instructions conform to the relevant and valid European Norm (EN) safety standards, as well as the current laws and regulations of the European Union. Qualified personnel are required for the proper application of these installation instructions. Qualified personnel are trained in the installation, mounting, commissioning, operation, and servicing of pneumatically and electrically actuated VG7000 Series Bronze Control Valves; they include trainers and instructors who have the following responsibilities: ensure adherence to regional and international ordinances and requirements teach safety standards enforce adequate facility safety and protective operation instruct first aid Location of Valve Data Each VG7000 Series Bronze Control Valve shipped from the factory includes a brass tag chained to the valve bonnet. The tag features technical data about the valve, including: code number of the valve flow coefficient Cv of the valve maximum allowable fluid temperature of the controlled media manufacturing date code of the valve (as illustrated in Figure 1) Refer to the QuickLIT website for the most up-to-date version of this document. Installation M y y Year Manufacturing Facility Figure 1: Manufacturing Date Code IMPORTANT: The VG7000 Series Bronze Control Valves are intended to control saturated steam, hot water, and chilled water flow under normal equipment operating conditions. Where failure or malfunction of the VG7000 Series Valve could lead to personal injury or property damage to the controlled equipment or other property, additional precautions must be designed into the control system. Incorporate and maintain other devices, such as supervisory or alarm systems or safety or limit controls, intended to warn of or protect against failure or malfunction of the VG7000 Series Valve. Pre-installation Details Before installing a VG7000 Series Bronze Control Valves, note the following: Be sure to mount the valve in an upright position, in a conveniently accessible location. Protect the electric actuator from dripping water that could enter the actuator housing and damage the mechanism or motor. Do not cover the actuator with insulating material. Allow sufficient clearance to remove the actuator (see Figure 2, Table 1, and Table 2). Pipe the valve with the flow in the direction of the arrow on the valve body, so that the plug seats against the flow. Wire all electrically actuated valve assemblies in accordance with applicable electrical code requirements. Input lines to the actuator must be wired correctly for the valve to move in the proper direction. w w Week FIG:mfgdtcd 1

2 IMPORTANT: Take care to prevent foreign material such as weld slag, thread burrs, metal chips, and scale from entering the piping system. This debris can damage or severely impede the operation of the valve by embedding itself in the seats, scoring the valve, and ultimately resulting in seat leakage. If the debris becomes embedded in the seats, subsequent flushing and filtering of the piping system with the valve installed does not remedy the problem.

Repair Information If the VG7000 Series Bronze Control Valve fails to operate within its specifications, refer to the VG7000 Series Bronze Control Valves Product Bulletin (LIT ) for a list of repair parts and reconditioning kits available. For a replacement valve, contact the nearest Johnson Controls representative. 5

6 Pre-servicing Details Before servicing a VG7000 Series Bronze Control Valve, isolate or disconnect the pneumatic supply or electrical power to the actuator and note the following: Risk of Electric Shock. Disconnect or isolate all power supplies before making electrical connections. More than one disconnection or isolation may be required to completely de-energize equipment. Contact with components carrying hazardous voltage can cause electric shock and may result in severe personal injury or death. Risk of Property Damage. Do not apply power to the system before checking all wiring connections. Short circuited or improperly connected wires may result in permanent damage to the equipment. Risque de dégâts matériels. Ne pas mettre le système sous tension avant d'avoir vérifié tous les raccords de câblage. Des fils formant un court-circuit ou connectés de façon incorrecte risquent d'endommager irrémédiablement l'équipement. Risque de décharge électrique. Débrancher ou isoler toute alimentation avant de réaliser un branchement électrique. Plusieurs isolations et débranchements sont peut-être nécessaires pour -couper entièrement l'alimentation de l'équipement. Tout contact avec des composants conducteurs de tensions dangereuses risque d'entraîner une décharge électrique et de provoquer des blessures graves, voire mortelles. Risk of Personal Injury. Shut off the liquid supply and relieve pressure in the line before servicing the valve. Contents of liquid lines could be under pressure and the release of liquid under pressure may cause severe personal injury. IMPORTANT: Make all wiring connections in accordance with local, national, and regional regulations. Do not exceed the electrical ratings of the VG7000 Series Bronze Control Valve. Valve Removal Details In addition to observing general mounting guidelines and National Code Standards, be sure to note the following before removing a valve from a piping system: Allow hot water or steam systems to cool down thoroughly before proceeding. Drain the piping system to provide a pressure-free work environment. Vent all piping systems that are used in conjunction with corrosive or aggressive fluids. Be sure all work is performed by qualified personnel only. Risque de blessure. Couper l'alimentation en liquide et évacuer la pression présente dans la conduite avant toute intervention sur la vanne. Les liquides à l'intérieur des conduites peuvent être sous pression et la libération soudaine de liquide sous pression risque de provoquer des blessures graves. 6
